Comments: I have had other reagent type test kits and they where not accurate. I bought this becouse of that. These are simple to use and seam to be accurate. The only thing was the PH did not come with any buffer solution to calibrate it.You will also need the solution to store the PH prob in. The phasphate only comes with 6 reagent packets.
<br />
<br />Pros: Easy to use and accurate.
<br />
<br />Cons: Only 6 test for the phasphate and could not use the PH probe becouse it did not come with the buffer solution to calibrate it.

Comments: Hard to use. it's easer to use Kent test kits. I'm not happy with this products I'm hoping that I can get my money back, the directions are not detailed instructions and hard to follow on 2 of the meters Calcium and the kh, Ph is ok and the phosphate is + - take it or leave it Kent products are easer to use
